Please note the flame are not from the liquid kerosine, they are from the kerosine vapor. The problem is the vapor and the solution is to stop the vapor production. Take out the heat. No vapor no fire. Pressurized water have to go on the base of the flame and not on the flame. I use garden pressure sprayer. I have make some tranning on big fire. Please belive me, the best, the most efficient is water at modeling level. It is easy to take a sprayer in the car.
